This is priceless.
A story at

reports that some scientists at Cambridge calculate that carbon emissions and global warming could stave off the next ice age, which would otherwise be due in 1500 years.
Some commentators on sites like Lucianne.com (http://www.lucianne.com/thread/?artnum=659420) and Hotair.com (http://hotair.com/archives/2012/01/09/only-you-can-save-earth-from-the-next-ice-age/)
are getting quite carried away with it; when they get tired of saying global warming is a hoax, they like to say OK, if it's not a hoax, then more C02 and warmer climate is a good thing.
Newsflash: C02 is not a poison (and no climate scientist thinks that it is) -- yes, it makes plants grow. Well, water is not a poison either, but flood victims all over the world (especially this past year) can tell you there is such a thing as too much water.
